Boris was my first attempt at building a fighting robot. It was impossible to control with any degree of accuracy. It lacked traction  and the weapon was ineffective. Not surprisingly, it lost every fight at its debut at "Rock & Robots".

Boris 2 was my next robot. This one had 4 wheel drive and a weapon that actually works! I did build a Boris 3, but found that it was not as good.  Boris 2 was beaten in most of its initial fights but amazingly won a 16 robot rumble at Rock & Robots 13. It now has a strip of acetate film along the front edge of the lifter and has recently won a few fights with my son Daniel at the controls.

As Boris 3 was a complete disaster, I decided to rework it as a wedgebot with flappy wedges both front and back. It will also operate inverted. There are no active weapons but practice fights with Boris 2 show that they are quite evenly matched.  This robot is close to the 150g limit for antweights, so I will build a lighter version and add an active weapon for Boris 4.
